OfficeToPDF

Sample C# code for using Apryse SDK to convert Office documents to PDF (including Word, Excel, PowerPoint and Publisher) without needing any external dependencies or MS Office licenses. Office to PDF conversion can be performed on a Linux or Windows server to automate Office-centric workflows, or entirely in the user's client (web browser, mobile device). The conversion functionality can be combined with our Viewer to display or annotate Office files (docx, xlsx, pptx) on all major platforms, including Web, Android, iOS, Xamarin, UWP, and Windows. Learn more about our Server SDK and Office Document Conversion Library.
